It L is a fluid filling the measuring-chambers opens into a chamber, T, and thence through H H, and more or less filling the expansionthe central ports in the valve-seat into the valves centrally between the orifices of the tubes S S and S S.

A is the outlet (or may be inlet) pipe. U U are slide-valves of ordinary construction.

V is the valve-seat, and XV XV guides. The

' valve-seat is inclined transversely at an angle of about forty-five degrees, and the orifices of the ports an d tubes are so disposed that no fluid suspended in the gas can trap the meter. The inclination of the valve-seat secures a drain age at its lower angle of inclination, which would be wanting in a valve-seat of other construction,while the weight of the valve,which would otherwise require a spring or other mechanical appliance to preserve its contact with the valve-seat, is sufficient to hold it in place. A free drainage at the valve-opening, and also along the tubes, is necessary to prevent the accumulation of a fluid before the flow of gas which would obstruct or prevent its passage. In order to prevent this in any degree, I make the outer ends, X, of the ports and the adjacent faces of the tubes S S and the chamber T horizontal, or dipping slightly-toward the exit.

In order to control the valves U U, I provide a crank-shaft, a, havin bearings and support in a chair, I), which is secured to the meter-case. V

c c are crank-disks, suitably secured on the ends of the crank-shaft a.

(Z is a crank-pin on the disk 0, and e a link connecting it with the valve U.

f is the link-pin on the valve. 9 is a double or set-off crank-pin on the disk 0, and is provided with two bearings, the inner one, serving for a link, h, connecting it with the valve U by means of the link-pin v This bearing has a quarter-lead on the crank-pin d. The outer bearing of the crank-pin 9 serves as a bearing for two links, and Z, and has an angular lead on the inner bearing equal to the mean divergence of the links 6 and h from the horizontal. The links it and Z connect the set-ofE portion of the crank-pin g with the arms 0 and 0, respectively, by means of the link-pins m and m. The pin m on the arm 0 of the yoke N isto one side of the screws 92, and the axis of the bearingpoints and perpendicular to the vertical screws H The pin m on the arm 0 of the yoke N is in the vertical axis of the yokes N N and as much below the axis of the bearingpoints as the center of pin m is to one side thereof. This construction gives the cups M M and M M and the corresponding valves a quarter-lead one on the other.

It will be observed that in Figs. 1, 2, and 3 the functional part of the meter is its lower half, and that the cups rest on their bearings, while in Figs. 5 and 6 the upper part is the functional part, and the cups are suspended from their bearings.

The difference between the two forms shown is this: That shown in Figs. 1 to 3, inclusive, is provided with a sealing-fluid, L, (necessarily a liquid,)'of specific gravity greater than that of the fluid to be measured, while the second form is provided with a sealing-fluid (either liquid or gas) of specific gravity less than that of the fluid to be measured. The first form is adapted (by using a proper sealing-liquid) to measure any known fluid except mercury, while the second form is of more limited application, being adapted to measuringliquids only, and especially designed as a water-meter, with the intention of using air as a sealing-fluid.

The fluid can pass through the meter by way of the tube T, the valves and the measuringcups entering the meter body after being measured and leaving through the tube A or can first enter the meter-body through the tube A and discharge through the tube T after being measured. The latter, however, is probably to be generally preferred,as any sediment which might be in the fluid would in the first case be deposited mainly in the cups, while in the second case it would be de-' posited in the m cter-body, whence it can be easily removed.

Having thus described my invention, I will now proceed to explain its operation. Suppose the meter to be properly set and connected with the supply and distributing pipes, and the fluid to be measured turned on. Suppose the fluid to enter through thetube T. It will find the valves in position so that it can pass by way of the valve recesses and ports and the corresponding tubes, S S to the corresponding cups, M M, ch. rging them with fluid, forcing them outward, while at the same time forcing the opposite cups, M M, into the liquid L and chamber II, discharging their contents through the corresponding tubes, S S, and valve-ports (now uncovered) into the meter-body, whence it escapes by the tube A This motion of the cups M M M M causes the crank-shaft a to revoke at the same time moving the valves and regulating the lead of the two sets of cups one on the other, and causing the cups to alternately charge through the valve-recesses, the covered ports, and the corresponding tubes, S S, and to discharge through the uncovered ports and corresponding tubes into the meter-body.

hen the meter is connected in the opposite way, the fluid entering the meter-body by the tube A finds one valve-port of each of the valves uncovered and passes through them and the corresponding tubes into the corresponding cups, M M, charging them and forcing them outward, while the opposite cups are forced into the liquid L and the measuring chamber, discharging their contents through the corresponding tubes, the valve-recesses, and the tube T. Of course this motion sets the crank-shaft a, &c., in revolution, but in the opposite way to that in which it revolves when the fluid is passing through in the way first described.

In order to remove sediment or other deleterious substance from the meter, I provide a receptacle, B and plug 0 in the lower part thereof. In Figs. 1, 2, and 3, D is a channel formed around the edge of the lower half to catch any such deleterious substance which might be condensed on the meter-case and convey it, by Way of the channel E to the aforesaid sedimentrreceptacle 13 \Vhat I claim is 1.
